A late season nor’easter soaked the northeastern United States on Monday. Heavy rain triggered flood alerts and advisories from Virginia to Connecticut, and areas further north reported snow.

Here in New York City, 0.70 inches of rain fell in Central Park. This came on the heels of the 1.32 inches that fell the day before when a separate storm system moved through the area. To date this May, the city has received 3.70 inches of rain and it is only the middle of the month. May, on average, brings the city a total of 4.19 inches of rain.

The storm also ushered in unseasonably cool temperatures, making it feel more like March than May. The high in NYC only made it to 48°F on Monday, setting a new record for the coldest high temperature for the date. The old record of 49°F was set in 1914. The normal high for this time of year is 70°F.

This storm was the result of a deep dip in the jet stream that moved over the region, which, in turn, helped generate an area of low pressure off the coast. Producing gusty northeasterly winds, it was categorized as a nor’easter. While this type of storm is more common during the fall and winter months, they can develop any time of the year.
